Do you own an electric vehicle?
Rust Check is completely safe for your Tesla, hybrid, or other electric vehicles. Our non-conductive formula protects the underbody and panels without interfering with high-voltage battery packs, electric motors, wiring, or system sensors.
The Nation's Most Reliable Auto Protection
Since 1973, Rust Check has been Canada's trusted choice for vehicle corrosion protection. Our Newmarket technicians apply a highly specialized, clean, oil-based formula that penetrates deep inside body seams, joints, and micro-crevices. Unlike thick undercoatings, Rust Check actively displaces moisture, neutralizes existing rust, and forms a self-healing barrier that keeps your vehicle structurally sound and preserves its resale value.

What Happens Without Rust Protection
Real-world examples of severe vehicle corrosion caused by road salt and Canadian weather.

Undercarriage & Structural Frame
Road salt, moisture, and chemical brines accumulate on your vehicle's frame. Without protection, structural steel weakens, posing major safety hazards and destroying resale value.
Rust Check penetrates deep into frame joints and subframes to stop structural steel decay and underbody rot.

"I’ve been taking my F-150 here for three years now. The salt in Newmarket winters is brutal, but thanks to this annual protection plan, my undercarriage still looks brand new. The oil spray penetrates everywhere and doesn't drip like others. Highly recommend Reagan and his team!"

"The peace of mind is worth every penny. I bought a brand new SUV and drove it straight to Rust Check. They were extremely fast, professional, and walked me through the coverage. It's a clean application, and the lifetime warranty is solid."

"Best investment you can make for a car in Ontario. My last sedan lasted 12 years with zero structural rust. The resale value was excellent when I traded it in. Great customer service at the Newmarket shop!"
